bdgdeviceRootPort
Module: CTRON-BDG-MIB
OID (symbolic): CTRON-BDG-MIB::bdgdeviceRootPort
OID (numeric): 1.3.6.1.4.1.52.1.3.1.1.22
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The port identifier for the port which offers the lowest cost path to the root, i.e. that port for which the sum of the values of the designated cost and path cost parameters held for the port is lowest.
What is bdgdeviceRootPort?
This read-only integer identifies which local port offers the lowest-cost path toward the spanning tree root bridge. An admin checks this to know which port is actively used to reach the root, which matters when planning changes that might affect that specific link. For example, if bdgdeviceRootPort shows port 1, the admin knows disconnecting port 1 would force the bridge to recalculate and potentially reach the root through a higher-cost alternate path, if one exists.
